Coulomb Explosion in Nanosecond Laser Fields [PDF]
The Journal of Physical Chemistry Letters, 2020 We report experimental observations of Coulomb explosion using a nanosecond laser at 532 nm with intensities less than 1012 W/cm2. We observe multiply charged atomic ions Arn+ (1 ≤ n ≤ 7) and Cn+ (1 ≤ n ≤ 4) from argon clusters doped with molecules containing aromatic chromophores.

Parameter optimization for enhancing TENG by UV nanosecond laser direct writing and coupling
Results in Engineering, 2022 TENG (triboelectric nanogenerator) has shown unique application prospect as a powerful way of harvesting renewable energy in micro-scale self-powered systems. The contact-separation (CS) arched TENG is so convenient that made a great progress in the past

Effects of picosecond laser on the multi-colored tattoo removal using Hartley guinea pig: A preliminary study. [PDF]
PLoS ONE, 2018 Picosecond lasers have emerged as the leading technology for tattoo removal due to their shorter pulse lengths. To clarify the features of picosecond lasers, we compared picosecond and nanosecond lasers in their ability to remove multi-colored tattoo in ...

Nanosecond laser treatment of graphene [PDF]
Applied Surface Science, 2013 Laser processing of graphene is of great interest for cutting, patterning and structural engineering purposes. Tunable nanosecond lasers have the advantage of being relatively widespread (compared to e.g. femtosecond or high-power continuous wave lasers). Hereby we have conducted an investigation of the impact of nanosecond laser pulses on CVD graphene.

Micromachining of polycrystalline CVD diamond-coated cutting tool with femtosecond laser
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2020 To enhance the cutting performance of chemical vapor deposit (CVD) diamond-coated tool, a short pulse laser grinding technique is applied. However, the thermal impact of a nanosecond laser damages the diamond crystallinity of the processed surface.
